Today was a really good day to listen to 88.5 WAMU FM. First Diane Rehm had graphic novelist Charles Burns was on discussing his book Black Hole. I almost bailed out on the interview as the two of them got off to a rough start. I'm glad I didn't because it really turned out to be a good interview. After Diane Kojo Nnamdi talked with mountaineer Arlene Blum about her journey from biochemist to scaling the world tallest peaks.
